The Supreme Court on Tuesday issued notice to the Centre and the Central Bureau of Investigation (CBI) on a petition seeking continuance of investigation into the alleged disproportionate assets of former Uttar Pradesh Chief Minister Mayawati.

The apex court also issued a notice to Mayawati.

The Supreme Court on July 6 this year had quashed an FIR filed by the CBI against Mayawati in the case.

Mayawati had filed a petition in May 2008 seeking quashing of the criminal proceedings against her in the case, alleging it was an act of political vendetta.

She claimed she had received the money through donations from party workers.

A bench headed by P Sathasivam had reserved its judgment on May 1 after two-hour-long hearing during which Mayawati had accused the CBI of fixing the DA case against her.

The CBI, on the other hand, has maintained that it has ample evidence to show that Mayawati had amassed wealth, disproportionate to her known sources of income.

Questioning Mayawati's assets, the CBI had said her declared assets of Rs one crore in 2003 had gone up to Rs 50 crore in 2007.

The CBI, in its last affidavit filed on September 13, 2011, had alleged there was a criminal nexus between Mayawati and her relatives and the disproportionate assets case against her cannot be closed on the basis of conclusions arrived at by the Income Tax Department. (ANI)
